[0032] Example

[0033] Please refer to Figure 1-4 This embodiment provides a torque detection device, including: a fixing mechanism for fixing a rocker arm to be tested and a torque detection module 88 for twisting the rocker arm to be tested to detect torque; wherein, the torque detection module 88 includes: a torque detection body 883 and a rotating head 882, the rotating head 882 is disposed at the rotation execution end of the torque detection body 883, and the rotating head 882 is provided with a pawl 881; the fixing mechanism is used to fix the rocker arm to be tested (such as...) Figure 4 The first part (as shown) is fed into the jaw 881 and fixed / restricted the rocker arm to be tested. The method of feeding into the jaw 881 includes inserting, clamping, embedding, or extending into the gap in the jaw 881. Further, the torque detection module 88 is used to apply torque to drive the rotating head 882 to twist the rocker arm to be tested in the jaw 881, and the torque is measured by the torque detection body 883 to obtain the torque of the rocker arm to be tested.

[0034] like Figure 1 In one embodiment shown, the opening of the jaw 881 is provided with an enlarged opening for guiding a portion of the rocker arm to be tested into the jaw 881. A gap is provided in the middle of the jaw 881, into which the rocker arm to be tested is fed. The jaw 881 can open and close to clamp the rocker arm. To facilitate the smooth feeding of the rocker arm to be tested into the gap of the jaw 881, an enlarged opening is specially provided. Furthermore, the enlarged opening is preferably an inverted V-shape, with the larger opening facing outwards to increase the area guiding the rocker arm to be tested.

[0035] like Figure 1-3In one embodiment, the torque detection module 88 can be configured as a movable mechanism, allowing it to move to accommodate the jaw 881, so that the jaw 881 can be fed into the rocker arm to be tested. In one example, the torque detection device includes a lifting mechanism 85, which drives the torque detection module 88 to move up and down to adjust the height of the jaw 881 to cooperate with the fixing mechanism; the torque detection module 88 is located at the execution end of the lifting mechanism 85. The lifting mechanism 85 can be mounted on a mounting plate 83, which is mounted on a first moving mechanism 86, as described below. In another example, the torque detection device includes a second moving mechanism 84, which drives the torque detection module 88 to move longitudinally to adjust the position of the jaw 881 to cooperate with the fixing mechanism; the torque detection module 88 is located at the execution end of the second moving mechanism 84. Similarly, the second moving mechanism 84 can be mounted on a mounting plate 83, which is mounted on a first moving mechanism 86, as described below. In another example, the torque detection device is provided with a first moving mechanism 86, which is used to drive the torque detection module 88 to move laterally to adjust the position of the claw 881 to cooperate with the fixing mechanism; the torque detection module 88 is located at the execution end of the first moving mechanism 86.

[0036] like Figure 1-3 In one embodiment shown, the fixing mechanism can be configured as a movable mechanism, allowing it to move to accommodate the gripper 881, so that the gripper 881 is inserted into the rocker arm to be tested. Specifically:

[0037] In one embodiment, the fixing mechanism is a pressing mechanism (not shown in the figures). The actuating end of the pressing mechanism is located below the rotating head 882 and is used to press the second part of the rocker arm to be tested to restrict the rocker arm from being sent into the chuck 881. The pressing mechanism pushes the rocker arm to be tested into the chuck 881, or the torque detection module 88 moves to allow the chuck 881 to be sent into the rocker arm. The pressing mechanism can be a linear drive mechanism such as a cylinder, electric cylinder, hydraulic cylinder, or ball screw. Its actuating end can push the rocker arm, and the actuating end can also be provided with a limiting groove or a clamp for mounting the rocker arm.

[0038] like Figure 1-3 In one embodiment shown, the fixing mechanism is a gripper mechanism 81, which is used to grasp and hold the third part of the rocker arm to be tested. The gripper mechanism 81 transfers the rocker arm to be tested into the jaw 881, or the torque detection module 88 moves to allow the jaw 881 to be inserted into the rocker arm to be tested. The gripper mechanism 81 has a handle 813, a gripper body 812 on the handle 813, and a driver and controller 811 connected to the gripper body 812 to control its opening and closing.

[0039] like Figure 1 , 2In one embodiment shown, the first moving mechanism 86 is configured as a first cylinder, with the push rod end of the first cylinder fixed. The torque detection module 88 and / or the gripper mechanism 81 are mounted on the first cylinder body. The first cylinder body has a vertically mounted mounting plate 83 for mounting the torque detection module 88, the lifting mechanism 85, the second moving mechanism 84, and the gripper mechanism 81. The torque detection module 88 is located on the first side of the mounting plate 83, and the lifting mechanism 85 is located on the first side of the mounting plate 83. The second moving mechanism 84 is mounted on the lifting mechanism 85. Thus, the lifting mechanism 85 drives the torque detection module 88 to move up and down to a preset position, and then the second moving mechanism 84 drives the torque detection module 88 to move back and forth to the preset position. The lifting mechanism 85 and the second moving mechanism 84 can be linear drive mechanisms such as cylinders, electric cylinders, or ball screws. The gripper mechanism 81 is located on the second side of the mounting plate 83, opposite to the torque detection module 88. A frame 87 is located below the first moving mechanism 86.

[0040] like Figure 3 In one embodiment shown, a second cylinder 82 is provided on the second side of the mounting plate 83 at an angle, and the actuating end of the second cylinder 82 is provided with a clamp 814 for holding the handle 813 of the gripper mechanism 81; the second cylinder 82 is used to adjust the posture of the gripper mechanism 81 gripping the rocker arm.

[0041] The torque detection device of this invention, after being moved to a suitable position to cooperate with the rocker arm to be tested by a drive mechanism (such as a first moving mechanism 86, a second moving mechanism 84, and a lifting mechanism 85), has its pawl 881 on the rotating head 882 clamping and rotating / twisting the rocker arm to be tested. During the rotation of a preset amplitude, the torque can be measured by the torque detection body 883 (which contains a torque sensor, a signal processor, and a controller 811, etc.). The torque detection module 88 can read the torque value parameter and rotate the rocker arm according to the preset value to evaluate whether the rotation / twisting is in place. In addition, the torque detection module 88 can also be moved above the rocker arm, with a pressing mechanism set below the torque detection module 88. The pressing mechanism presses against the grooves on both sides of the rocker arm, and the pawl 881 on the rotating head 882 rotates / twists the rocker arm, while the torque detection body 883 detects the resistance and torque value of the rocker arm.

[0042] This utility model's torque detection device, through its unique design and flexible adjustment mechanism, improves the efficiency and accuracy of torque detection, while enhancing the device's versatility and automation, providing strong support for torque detection of components such as rocker arms. Specifically:

[0043] 1. Improved detection efficiency and accuracy: Through the coordinated work of the fixing mechanism and the torque detection module 88, the rocker arm to be tested can be stably fixed and torque can be applied for detection, thereby improving the efficiency and accuracy of torque detection.

[0044] 2. Flexible adaptation to rocker arms of different sizes: The design of the 881 jaw has an enlarged opening and a gap, especially the inverted V-shaped enlarged opening, which can easily guide rocker arms of different sizes to be tested into the 881 jaw, enhancing the versatility and adaptability of the device.

[0045] 3. Easy to operate and adjust: Both the torque detection module 88 and the fixing mechanism can be set as movable mechanisms (achieved through the drive mechanism). With the setting of the lifting mechanism 85, the second moving mechanism 84 and the first moving mechanism 86, the position of the claw 881 and the fixing mechanism can be flexibly adjusted to adapt to different detection needs and spatial layouts, thus improving the convenience and flexibility of operation.

[0046] 4. Diverse Fixing Methods: The fixing mechanism can employ either a pressing mechanism or a gripper mechanism 81. Both methods effectively restrict the movement of the rocker arm to be inspected, ensuring the stability of the rocker arm during the inspection process. Simultaneously, the gripper mechanism 81 can also transfer the rocker arm to be inspected, further improving the automation level of the inspection.

[0047] 5. Function of adjusting the posture of the gripper mechanism 81: The posture of the gripper mechanism 81 in grasping the rocker arm can be easily adjusted by the second cylinder 82 and its clamp 814 that are inclined on the mounting plate 83, which further improves the flexibility and adaptability of the device.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
